1, AC motor asynchronous

I-AC asynchronous motor yimoto yombane ehamba phambili ye-AC, esetyenziswa kakhulu kwiifeni zombane, iifriji, oomatshini bokuhlamba, i-air conditioner, izomisi zeenwele, izicoci zokucoca, iihoods, oomatshini bokuhlamba izitya, oomatshini bokuthunga bombane, oomatshini bokulungisa ukutya kunye nezinye izixhobo zasekhaya, njengoko kunye nezixhobo zombane ezahlukeneyo kunye nezixhobo zombane ezincinci.

I-AC ye-asynchronous motor yahlulwe kwi-induction motor kunye ne-AC commutator motor.I-motor induction yahlulwe yangakwinqanaba elinye le-asynchronous motor, i-AC / DC motor kunye ne-repulsion motor.

Isantya se-motor (isantya se-rotor) singaphantsi kwesantya se-magnetic field ejikelezayo, ngoko kuthiwa yi-asynchronous motor.Ngokusisiseko iyafana nemoto yokungenisa.S = (ns-n) / NS.S lizinga lokutyibilika,

I-NS yisantya semagnethi kwaye i-N isantya serotor.

Umgaqo osisiseko:

1. Xa inqanaba lesithathu lenqanaba le-asynchronous motor liqhagamshelwe kwisigaba sesithathu sombane we-AC, inqanaba lesithathu le-stator elijikelezayo liqukuqela ngamandla amanqanaba amathathu emagnetomotive (i-stator ejikelezayo ye-magnetomotive force) eveliswa yi-symmetrical current yesigaba sesithathu kwaye ivelisa. indawo ejikelezayo yemagnethi.

2. Intsimi yamagnetic ejikelezayo inentshukumo yokusika isalamane kunye ne-rotor conductor.Ngokomgaqo wokungeniswa kwe-electromagnetic, i-rotor conductor ivelisa amandla e-electromotive kunye ne-induced current.

3. Ngokomthetho we-electromagnetic force, i-rotor conductor yangoku ichaphazelekayo ngamandla e-electromagnetic kwintsimi yamagnetic ukwenza i-torque ye-electromagnetic kwaye iqhube i-rotor ukuba ijikeleze.Xa kukho umthwalo womatshini kwi-motor shaft, iya kukhupha amandla oomatshini ngaphandle.

I-Asynchronous motor luhlobo lwe-AC motor, kwaye umlinganiselo wesantya phantsi komthwalo ukuya rhoqo kwigridi yamandla edibeneyo ayitshintshi.Ikwatshintsha kunye nobukhulu bomthwalo.Inkulu i-torque yomthwalo, isantya esisezantsi se-rotor.I-Asynchronous motor ibandakanya i-induction motor, i-motor induction ephindwe kabini kunye ne-AC commutator motor.Injini yokungenisa yeyona isetyenziswa kakhulu.Ngokuqhelekileyo inokubizwa ngokuba yi-asynchronous motor ngaphandle kokubangela ukungaqondi okanye ukudideka.

I-stator winding ye-motor ye-asynchronous eqhelekileyo ixhunywe kwigridi yamandla e-AC, kwaye i-rotor winding ayifuni ukudibaniswa kweminye imithombo yamandla.Ngoko ke, ineenzuzo zesakhiwo esilula, ukuveliswa okulula, ukusetyenziswa kunye nokugcinwa, ukusebenza okuthembekileyo, umgangatho ophantsi kunye neendleko eziphantsi.I-Asynchronous motor inokusebenza okuphezulu kunye neempawu ezilungileyo zokusebenza.Isebenza ngesantya esingaguqukiyo ukusuka ekungangeni mthwalo ukuya kumthwalo opheleleyo, onokuhlangabezana neemfuno zothumelo lwemveliso emininzi yoomatshini kunye nemveliso yezolimo.Iinjini ze-Asynchronous zikwalula ukuvelisa iintlobo ezahlukeneyo zokukhusela ukuhlangabezana neemfuno zeemeko ezahlukeneyo zokusingqongileyo.Xa i-asynchronous motor isebenza, amandla okuvuselela asebenzayo kufuneka afunwe kwigridi yamandla ukuze wonakalise amandla ombane wegridi.Ke ngoko, iimotor ezilungelelanisiweyo zihlala zisetyenziselwa ukuqhuba izixhobo ezisebenza ngamandla aphezulu kunye nesantya esisezantsi njengeebhola zebhola kunye neecompressors.Ngenxa yokuba isantya semoto ye-asynchronous inobudlelwane obuthile bokutyibilika kunye nesantya semagnethi esijikelezayo, ukusebenza kwayo kokulawulwa kwesantya kubi (ngaphandle kwemoto yokuhambisa i-AC).Imoto ye-DC inoqoqosho ngakumbi kwaye ilungele oomatshini bothutho, ilitye lokusila, isixhobo esikhulu somatshini, ukuprinta kunye nokudaya kunye noomatshini bokwenza amaphepha abafuna uluhlu olubanzi nolugudileyo lolawulo lwesantya.Nangona kunjalo, ngophuhliso lwezixhobo zombane ezinamandla aphezulu kunye nenkqubo yokulawula isantya se-AC, ukusebenza kommiselo wesantya kunye noqoqosho lwemoto ehambelana neasynchronous efanelekileyo kulawulo lwesantya esibanzi xa ithelekiswa nemoto yeDC.
